We didn't crate train our last dog Shadow. We paper trained her. This works for some, although not everybody advocates it. Looking back at the webcam stuff I saw, were the puppies encouraged to go on paper? This might help.

We gradually moved the paper outside the back door, and on to the grass. Then just eliminated the paper.

But lots of people swear by crate training.
